五轮仪设计中的几个问题

Some Problems in Designing of the Fifth-Wheel Meter

作者在改进设计工程车辆重要试验设备—五轮仪的过程中,解决了WLY—4型五轮仪存在的几个问题,其一是检测工程车辆超低速的问题;其二是简化了在测试中的标定过程,提高了标定精度;其三是仪器易磨损的轮子的更换问题;进一步拓宽了五轮仪的应用范围.

In this paper,the author narrates how to solve some problems of type WLY-4 of the fifth-wheels meter.During improving ang designing the fifth-wheel meter,it is an improtant testing equipment for engineering vehicle.The first problem is to test the ultralow speed of engineering vehiele.Secondly,the scalar process is simplified in testing,and then its precision is increased.And the third is the exchanging of the wheel which is easily torn and worn so that,the field of application of the fifth-wheel meter is extended.
